Unused to terror strikes of such sophistication and global reach, the Delhi Police was on Tuesday struggling to get leads in the bomb attack on an Israeli diplomat's car near the city's Aurangzeb Road crossing.

Twenty-four hours after the attack, the nature of explosive material used in the sticky bomb remained unknown.

International assistance arrived in the form of a team from Israel’s external intelligence agency Mossad, which is assisting the Delhi Police and the National Investigation Agency (NIA). The US Federal Bureau of Investigation also offered help, though no formal request had been made so far.

The attack took place on Monday, with a motorcycle-borne bomber sticking an explosive to an Israeli embassy car at a traffic signal less than 300 metres from the prime minister's residence and fleeing.
